Parmesan Chicken

One of the things that can be dispiriting about skinless, boneless chicken breasts is that they lack the luscious contrast between crisp golden skin and moist, tender meat. Not here. We use English muffin crumbs and Parmesan to make a coating for the chicken. This is classic comfort food without too much fat.
The chicken can marinate in the mustard mixture, covered and refrigerated, for up to two hours.
